ATP is a an important molecule for its major function___________?

Correct answer: A. As an energy currency of the cell

  • A. As an energy currency of the cell
  • B. As a coenzyme
  • C. Both a and b
  • D. None of these

Explanation

ATP stores usable chemical energy in its phosphate bonds and transfers that energy to cellular processes, so it is called the energy currency of the cell. It can participate in some enzyme reactions, but its major biological role is energy transfer rather than acting as a coenzyme. Students may choose c by treating every molecule involved in an enzyme reaction as a coenzyme.
